IMPROVEMENT lN RECIPROCATING CHURNS.

Specification forming part of Letters Patent No. 194,865, datedSeptember 4, 1877; application filed March 3, 1877.

To all whom it may concern Be it known that we, GROVNER GOFF and HENRYHARDIGK, of Stevensville, in the county of Sullivan and Statejof NewYork, have invented a new and Improved Churn tljfotion, of which thefollowing is a specificaion:

In the accompanying drawing, Figure 1 represents a vertical longitudinalsection of our improved churn-motion, taken on line mm, Fig. 2; and Fig.2 is an end elevation of the same.

Similar letters of reference indicate corresponding parts.

The object of our invention is to furnish for dalrymen an improvedchurn-motion. bywhich a uniform stroke is imparted to the dasher of thechurn with little effort, the length of the stroke being readilyadjusted as required.

The invention will first be described in connection with the drawing,and then pointed out in the claim. In the drawing, A represents thesupportlng-frame of our improved churn-motion, to one end of which arevolving crank and flywheel, B, turns in suitable bearings.

The crank-wheel Brevolves, by a gear-wheel, a, and pinion b, of smallersize, a double-crank shaft, 0, with fly-wheel O, to the slottedcrankarmsD of which the pitman is secured in adjustable manner.

The opposite end of pitman E is pivoted to the lower slotted end of anelb0w-lever,F, that is fulcrumed at its angle to a pivot at the top partof frame A.

The connecting ends of pitman E and elbowlever F are provided withseveral holes, so that the pivotconnection may be placed at a higher orlower point, for the purpose of producing small changes in the stroke ofthe dasher, which is pivoted to the similarly-perforated upper end ofthe elbow-lever.

The adjustment of the pitman in the slotted double crank D admits thelengthening or shortening of the stroke when a considerable change inthe same is necessary, while by raising the pitman in elbow-lever thestroke will be more in an upward direction, and by lowering the pitmanthe stroke will be more in a downward direction.

The pitman-connection of the crank-shaft with the elbow-lever changesthe rotary motion of the hand-crank wheel into the reciprocating motionof the elbow, for working the dasher, the fly-wheels, andtransmitting-gearing, facilitating the working of the churn. so that thesame may be run with but little effort by any one, producing a uniformand effective stroke of the dasher, and facilitating and acceleratingthe churning operation.

The device is readily applied to the churn, always in order for work,easily adjusted, and effective in operation.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent The combination, with a pitman. E, pivoted atthe front end to a swinging elbow-lever, F, of the double-cranked rotarydrive-shaft 0, having arms, D, slotted, as shown and described, toregulate the throw of the pitman to correspond with any change in thestroke of dasher.
